Kudos to team 1662 for making this style of shifting dog gear. I've always wanted to try out this press-fit-dowel style, and only have depended on hearing how this performs from 1-2 other teams who have done it.

Team 229 did this in 2003, and I believe a few other teams have tried it.

I think I see that there are standard steel dowels pressed into an aluminum disc to make up the dog gear. Is this true?

If you don't mind, I have a few questions:

1. How much of an interference press fit exists between the steel dowels and the aluminum holes? (I am guessing it is 0.001" or 0.0005")

2. What is the size of the dowels? (diameter and length)

3. The shaft that the aluminum disc slides on appears to be square... is it 1/2" wide? If not, what is that thing?

4. How much stroke is needed for a shift?

Like I said above, good job on this. Thanks for sharing the pictures.
